Yes, done it, several times. Although that was done over a leased
satelite link. Any other ip-traffic had a lower priority...

Had a number of hardphones (snom's & utstar's) at one end, and asterisk
via ipsec-tunnels at the other end.
In between a C-band satelite and a small tracking antenna on moving
vehicles (cars and ships)

Latency is noticable, but acceptable.
Choise of codecs determine the number of available channel, given an
amount of bandwith, obviously
